If you are reporting a bug to http://bugs.kde.org, ensure you write down the current version of your KDE prerelease, from which source it was obtained, and if possible, detailed steps on how to reproduce the issue. In case you have a crash, install the debug symbols packages (-dbg in Ubuntu, -debugsource/-debuginfo on openSUSE) and reproduce the crash. Use the Bug report wizard to submit the crash backtrace to KDE's bug tracker.
